In SQL Server you would write it as

if exists (select 1 from myTable where ClientStat = 'A')
your logic

but I believe this syntax is invalid for VFP.

>this works fine. but just that i cant think of a statement in the event there is no A,B C or D in the data base. SO if i select OGStatus and the table has no "A" the report only flashes :( im trying to think of a statment to stop that
If it's not broken, fix it until it is.
